Windshield washer and wiper assembly

ABSTRACT

A windshield washer and wiper assembly for cleaning a windshield of an automobile. The assembly is generally comprised of an elongated housing, a source of windshield washer fluid under pressure, a perforated bladder within the housing, means for washing the windshield mounted through the housing in contact with the bladder, a wiper blade mounted on the housing and means for deflating the bladder. The bladder, upon actuation of the washer fluid source, inflates with washer fluid, urging the washing means against the windshield while simultaneously disengaging the wiper blade from the windshield and leaking washer fluid onto the windshield. The bladder returns to a contracted state by the deflating means upon deactivation of the washer fluid source to return the wiper blade to the windshield surface.

This application is a continuation-in-part application of a previous application by the same inventor bearing U.S. Ser. No. 08/950,830 filed Oct. 15, 1997, now U.S. Pat. No. 5,799,359. The entire previous application is incorporated herein by reference as if set forth in full below.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an assembly for washing and wiping the windshield of an automobile, particularly an improved windshield washer and wiper assembly capable of removing solid matter such as dried insect debris from the windshield of an automobile.

2. General Background

All automobiles are equipped with windshields or wind screens which require periodic cleaning while the vehicle is in operation. All such vehicles are likewise equipped with windshield wipers which are adapted to move in a back-and-forth motion in order to sweep across a major portion of the windshield and remove water therefrom. Conventional windshield wipers are adapted to function in a "squeegee" manner--that is, the rubber windshield wiper blades scrape across the windshield surface and remove water therefrom. Most automobiles produced after the early 1970's are also provided with windshield washer fluid delivery systems, wherein cleaning fluid may be delivered under pressure to the windshield to aid the windshield wipers in removing dirt or dust therefrom. Windshield wipers have been designed so that they bear against the windshield with a moderate amount of force sufficient to sweep the surface of the windshield clean, but generally not enough to effect any scrubbing action by the wiper blade, since the purpose of the wiper blade is to remove water.

The problem that has existed for some time is that when solid matter such as flying or airborne insects impact against the windshield of a rapidly moving automobile, the body fluids of the insect, and to some degree the exterior body parts, adhere to the windshield and are quickly dried thereon. The resulting windshield smear is, for the most part, impossible to remove by the squeegee action of a conventional windshield wiper blade, even when assisted with windshield washing fluid.

Several devices have been patented which are aimed at removing solid matter from the windshield of an automobile.

Patent Cooperation Treaty (PCT) International Publication No. WO 80/01155 discloses, as best seen in FIGS. 2-4, a combination scrubber/wiper system for a vehicle windshield that has a jacking means 14 which, in use, can urge brush 44 toward and against windscreen 48, then causing the wiper blade 10 to be lifted out of contact with windscreen 48, and can cause or permit withdrawal of brush 44, thereby permitting the wiper blade 10 to reengage windscreen 48. Jack 14 is pneumatically actuated with a spring return 37; in particular, cylinder 26 is connected by passage 36 to hose 38 through which air can be supplied and exhausted to actuate jack 14. Also, the operation of the device is associated with the operation of a windscreen washer, as water can be delivered through a perforated pipe extending along the length of brush 44.

U.S. Pat. No. 4,649,593 issued to J. C. Gilliam, III, et al., and entitled "Windshield Wiper And Cleaner" teaches, as best disclosed in FIGS. 1-3, a combined windshield wiping and cleaning device that has a scrubbing member 3 with a reticular surface 7 covered by mesh 6 for removing solid matter along with a wiper blade 2 for squeegee removal of water. Scrubber 3 and wiper blade 2 are formed together with a supporting base as a single monolithic extrusion 1 of an elastomeric material which fits into the windshield wiper arm in the conventional manner.

U.S. Pat. No. 4,567,621 issued to R. L. Alley, Jr., and entitled "Composite Windshield Wiper Assembly" discloses, as best seen in FIGS. 2, 4 and 5, a windshield wiper assembly that also has a window wiper and scrubber in combination as an integral unit. The assembly A has a pair of spaced wiper blade elements 42 and 44 having thin resilient wiping edges 42a and 44a, respectively, and scrubbing block 50 in the space between blade elements 42 and 44. The scrubbing block 50 includes a protrusion 52 which extends past the wiping edges 42a and 44a to provide a light scrubbing action against windshield 12.

U.S. Pat. No. 4,327,457 issued to Dayco Corporation on the application of B. R. Lunsford and entitled "Windshield Wiper And Method Of Making Same" discloses, as best seen in FIGS. 1, 4 and 8, another window wiper and scrubber combination 30 which comprises a pair of wiping members 32 in spaced-apart relationship and a cleaning member 33 disposed therebetween, cleaning member 33 has a semi-cylindrical portion 35 which is adapted to engage the windshield surface 12 roughly midway between wiping members 32 during cleaning movements of the device.

U.S. Pat. No. 3,849,827 issued to The B.F. Goodrich Company on the application of J. P. Coropolis, et al., and entitled "Window Washer Seal Assembly" discloses, as best seen in FIGS. 1-3, a windshield wiper assembly 10 that inflates so that the wipers 12 and 13 engage the surface of the windscreen 25 yet at the same time sprays washer fluid 37 from reservoir 36. An inflatable resilient tube or bladder 11 carries the pair of blades 12 and 13 engagable with the windscreen 25. Washer fluid 37 is pumped (35) into the tube 11 between blades 12 and 13 and ejected through the holes 26 in the tube 11. One of the blades 12 or 13 may extend into engagement with windscreen 25 in the deflated condition of tube 11 for sealing the space between the tailgate and windscreen 25 and at least one of the blades 12 or 13 may be brought into wiping engagement with windscreen 25 upon inflation of tube 11 during the washing operations.

Other patents present in the art are U.S. Pat. No. 4,060,872 entitled "Windshield Wiper And Washer"; U.S. Pat. No. 3,871,049 entitled "Window Wiper Assembly"; and U.S. Pat. No. 4,754,517 entitled "Windshield Wiper Blade"; all of which are directed to cleaning a windshield of an automobile, but do not meet the needs of the assembly of the present invention.

The apparatus of PCT International Publication No. WO 80/01155 is overly complex, requiring a source of compressed air to actuate the device. Furthermore, the device is not easily installed on the wiper arm of an automobile; the device must be mounted with bolts.

The devices of U.S. Pat. Nos. 4,649,593; 4,567,621; 4,327,457; 3,849,827; 4,060,872; 3,871,049; and 4,754,517 all do not use conventional wiper blades such as come equipped with an automobile. Furthermore, the devices of U.S. Pat. Nos. 4,327,457; 3,849,827; and 3,871,049 are designed to work on non-oscillating wiper arms. Also, the devices of U.S. Pat. Nos. 4,327,457; 3,849,827; 4,060,872 and 3,871,049 do not use a brush to clean solid matter from the windshield of an automobile.

Thus, a need exists for a windshield washer and wiper assembly for cleaning solids from the windshield of an automobile which combines the function of cleaning and scrubbing solid matter with the function of wiping and squeegee removal of fluid in a single element through the proper combination of scrubbing, fluid application and squeegee action.

A need also exists for an assembly with the above features which is easily installed and operated in the standard wiper arm assembly now commonly used to perform only the wiping or squeegee removal of water on the windshield of an automobile.

A need also exists for an assembly with the above features which can use a conventional wiper blade such as comes equipped with an automobile.

Also, a need exists for an assembly with the above features which operates on an oscillating wiper arm of an automobile.

A need also exists for an assembly with the above features which is simple in design and easy and economical to manufacture.

SUMMARY OF THE PRESENT INVENTION

The preferred embodiment of the assembly of the present invention solves the aforementioned problems in a straight forward and simple manner. What is provided is an assembly for washing and wiping a windshield of an automobile, the automobile having a windshield wiper arm affixed to motor means for moving the wiper arm in an oscillating motion and the assembly comprising an elongated housing, a bladder within the housing, a source of windshield washer fluid under pressure, means for washing the windshield mounted through the housing, a wiper blade mounted on the housing and means for deflating the bladder.

The housing has a top side, bottom side, front side, rear side, and a pair of ends. One of the ends has a hole for coupling the housing to the washer fluid source. A slot runs the length of the bottom of the housing. The housing has a series of grooves spaced intermittently along the length of the housing. The grooves run through the front side, top side and rear side and are perpendicular to the slot. The housing has first mounting means for slidably mounting the housing to the wiper arm of the automobile, the first mounting means being mounted on the top side of the housing. The housing also has second mounting means for slidably mounting the wiper blade to the bottom side of the housing, the second mounting means being mounted on the rear side and the bottom side to the rear of the slot.

A bladder is located inside the housing. The bladder has an outlet which extends through the hole in one end of the housing and couples the washer fluid source to the bladder. A series of perforations runs the length of the bladder. The bladder is normally in a deflated state.

The washing means is mounted through the slot in the housing and in contact with the bladder. The washing means is not in contact with the windshield when the bladder is deflated.

The wiper blade is a conventional wiper blade such as comes equipped on automobiles and is in contact with the windshield when the bladder is deflated.

The deflating means deflates the bladder when the washer fluid source stops supplying washer fluid to the bladder, causing the washing means to disengage the windshield and the wiper blade to reengage the windshield.

In operation, the assembly is slidably mounted on the wiper arm of the automobile such that the wiper blade and the washing means are facing the windshield, with the wiper blade engaging the windshield and the washing means not engaging the windshield. The source of windshield washer fluid under pressure is coupled to the bladder through the outlet in the bladder. Upon actuation of the source of windshield washer fluid under pressure, the washer fluid source supplies washer fluid under pressure to the bladder. The bladder inflates with washer fluid, urging the washing means outwardly against the windshield. As the washing means engages the windshield, the wiper blade is simultaneously disengaged from the windshield. Washer fluid leaks from perforations in the bladder through the housing and down the washing means to wet the windshield. As the wiper arm moves back and forth in an oscillating motion, washer fluid wets the windshield and the washing means scrubs solid matter from the windshield, thereby cleaning the windshield. After a predetermined time, the washer fluid source stops supplying washer fluid to the bladder. The deflating means deflates the bladder, retracting and disengaging the washing means from the windshield and reengaging the wiper blade to the windshield. The oscillating motion of the wiper arm allows the wiper blade to wipe away any remaining washer fluid from the windshield.

In view of the above, it is an object of the present invention to provide a windshield washer and wiper assembly for cleaning solids from the windshield of an automobile which combines the function of cleaning and washing solid matter with the function of wiping and squeegee removal of fluid in a single element through the proper combination of washing, fluid application and squeegee action.

It is a further object of the present invention to provide such an assembly with the above features which is conveniently installed and operated in the standard wiper arm assembly now commonly used to perform only the wiping or squeegee removal of water on windshields.

It is another feature of the present invention to provide an assembly with the above features which can use a conventional wiper blade such as comes equipped with an automobile.

Another object of the present invention is to provide an assembly with the above features which operates on an oscillating wiper arm of an automobile.

In view of the above objects it is a feature of the present invention to provide an assembly with the above features which is simple in design and easy and economical to manufacture.
